12.6 Film mode detection
What can be done ?
Some sources like common DVD material are derived from cinema 24 Hz sources (2/2 or 3/2 pull down method).
The film mode detection insures that these converted signals are shown without artefacts.
This function may cause undesired effects on standard sources, therefore it can be disabled (OFF) at any time
2:2 pull-down
The process of transferring 24-frames/sec film format into video by repeating each frame (used for PAL DVD’s) as two
video fields. ( AD )
3:2 pull-down
Method used to map the 24 fps of film onto the 30 fps (60 fields) or 25 fps (50 fields), so that one film frame occupies
three video fields, the next two, etc. It means the two fields of every other video frame come from different film frames
making operations such as rotoscoping impossible, and requiring care in editing. Some sophisticated equipment can
unravel the 3:2 sequence to allow frame-by-frame treatment and subsequently re-compose 3:2. The 3:2 sequence
repeats every five video frames and four film frames, the latter identified as A-D. Only film frame A is fully on a video
frame and so exists at one time code only, making it the editable point of the video sequence.
